VCN 3.1.1 never existed in the first place, was a jebait as far as we're concerned. VCN4 is what Rembrandt features.
Also I've said it before, I'll say it again. Rembrandt exists for the premium thin and light market first, the thin and light gaming market second and everything else a very distant third.
Want a budget thin and light? Buy Alder Lake-M.
Want a high power gaming laptop? Buy Alder Lake-P.
If AMD decide to compete in that market sure.Premium is a given because of the DDR5/LPDDR5 limitation this year. Yes seems like for a big iGPU increase in the mainstream/mass notebook segment we have to wait for next year.
Cezanne gets almost no bump to GPU performance from anywhere above 1.5GHz. Look at how little improvement there was over the 4800U.The real kick in the family jewels is the 5850u. It gets +100Mhz max boost on the CPU (with a max power envelope of 15w) and a -200Mhz CUT to the iGPU! Why would I EVER choose the 5850u over an older, and likely cheaper SKU, that has the 5800u with more MHZ where it is most needed, the iGPU? you will NEVER feel that 100mhz on the CPU. If Barcelo is a refinement of Cezanne, why reduce performance unless you are deliberately sandbagging the product to protect the higher end of the stack? They could have made it LPDDR4X focused and pushed the iGPU to 2.1Ghz (which it is certainly capable of doing) and left the max CPU boost alone.
PRO SKUs got different iGPU configs for Renoir if I remember correctly. This is just same thing again.Something isn't adding up with the SKU leak... Lenovo's Thinkpad website for the new Z series models has...
AMD Ryzen™ PRO 6000 H Series Mobile Processors:
That R7 PRO with 8GPU cores... I didn't see that in the leaked slide... Could that be 2 segments with 2 activated WGPs instead of 2 segments with 3 WGPs like in the 12 CU model?
- R9 PRO – 8 cores, 16 threads + 12 GPU cores
- R7 PRO – 8 cores, 16 threads + 8 GPU cores
- R5 PRO – 6 cores, 12 threads + 6 GPU cores
Or is it just a typo? Maybe a late change in segmentation that Lenovo didn't catch or AMD didn't correct on the slide?
That s an "incentive" to use their low end 12/16 CUs RDNA2 dGPU, both would suit a 6C SKU while the 16 CUs one would fit the 8C/8CUs part.The biggest problem with the IGP segmentation is that the whole point of the DDR5 premium is the IGP perf, and 6CU completely defeats that. What were they thinking? i dont get it. They had the chance to do 10 and 8CU SKUs, instead they go directly to 6, what may mean 2MB not 4MB of L2 as well.
Strange as I have played with my brother's HP laptop with Ryzen 5800U just two weeks ago ...6800U will have zero real availability, just like 5800U and 4800U before it.
Is it an HP Pavilion Aero? Because that's one of the three or four laptops with the 5800U that is available in my country.Strange as I have played with my brother's HP laptop with Ryzen 5800U just two weeks ago ...
He bought it for coding and he was blown away by the speedup compared to Ryzen 4500U, like 4X+ faster.
Its going to be faster than Vega 8, specially the Vega 8 sku below it that has a reduced IGP clock boost vs the old gen.Even though 12CU performance is more a vaporware in the meaningful iGPU notebook segment, I would like to see a performance comparison with Vega 8 and Iris Xe 96EU, I wonder if we will see a test or something.
Not necessarily. Rembrandt is on 6nm. Zen 3 is on 7nm, and Zen 4 is on 5nm. AMD is splitting their product stack up between different nodes, which should increase supply barring no other constraints. Right now, EVERYTHING is on 7nm.6800U will have zero real availability, just like 5800U and 4800U before it.
AMD claimed double the performance at 1080p for the 6800U vs the 5800U.
Based on testing by AMD as of 12/14/2021. CPU performance evaluated with a geomean of 9 multi-threaded content creation and CPU tests. GPU performance evaluated with 3DMark® Time Spy. System configuration for Ryzen™ 7 5800U CPU/GPU performance: HP ProBook 635 Aero G8 configured with 2x8GB DDR4-3200 (22-22-22), Windows® 11 22000.282, Samsung 980 Pro 1TB SSD, 15W nominal processor TDP, GPU driver 27.20.21026, BIOS T83. System configuration for Ryzen™ 7 6800U CPU/GPU performance: AMD reference motherboard configured with 4x4GB LPDDR5-6400 (19-15-17), Windows® 11 22000.282, Samsung 980 Pro 1TB SSD, 28W nominal processor TDP, GPU driver 30.0, BIOS TRM0081D.

RAM speed improvement has about zero influence for CB.DDR5 might be the reason the MT performance increases so much (besides 6nm and power optimizations of course). It offers higher bandwidth and parallelism with 2x as many channels.
Or maybe something in the core or L3 was tweaked when it was being ported from N7 to N6?
Scummiest comparison from AMD in a while, they always disappoint like this recently.5800U DDR4-3200 22-22-22 vs 6800U LPDDR5-6400 19-15-17
5800U 15W vs 6800 28W
Zero about the Iris Xe device, probably DDR4
But it's AMD, it's fine. If Intel does this the forum explodes.
